  2. ebXML • ebXML is a global e-business standard • It is a framework that will allow businesses to find each other and conduct business based on well-defined XML messages governed by standard or mutually-negotiated partner agreement • Sponsored by UN/CEFACT (United Nations Center for Trade Facilitation and Electronic Business) and OASIS (Organization for the Advancement of Structural Information Standards)

  3. ebXML System overview • 3 Key phases: Registration/ImplementationDiscoveryNegotiation • ebXML Registry

  4. ebXML Registry • Central storage of business information, e.g. business process descriptions, XML schemas, CPPs, etc. • CPP (Collaboration Protocol Profile) - a profile filed with a Registry by a business wishing to engage in ebXML transactions. The CPP will specify some Business Processes of the business, as well as some Business Service Interfaces it supports.

  5. Registration/Implementation • A company will access the Registry to examine existing Business Processes and Business Scenarios • A company will build and publish its Collaboration Protocol Profile (CPP), including its Business Process Information

  6. Discovery • In this phase a company will use the Registry to discover business processes and interfaces published by other trading partners. • A company will generate and send a Collaborative Partner Agreement (CPA) to a trading partner • CPA is a reflection/intersection of both companies’ CPPs. • CPA contains information about messaging requirements for transactions, the conversations that take place in a collaborative business process, contingency plans, and security-related requirements.

  7. Negotiation • The resulting CPA is submitted to a trading partner and is used to configure the runtime systems of both companies. • After the trading partner accepts the CPA, both companies are ready to engage in e-business using ebXML • The transactions consist of ebXML messages, which are sent over the standard ebXML Messaging Service • ebXML MS utilizes SOAP and HTTP (it also allows for attachments)

  8. ebXML functional model

  9. ebXML Case Study Nuts and Bolts
